It would not be difficult at all to add that comparison; as simple as adding an extra capture of table columns and column #'s. I'd be happy to consider adding that in. Note that pgcmp expects the database to be captured as databases; it pulls data from information_schema and such. In order to run it against a pair of dumps, you'd need to load those dumps into databases, first. -- When confronted by a difficult problem, solve it by reducing it to the question, "How would the Lone Ranger handle this?"
